Guess the mark: a Solent racing-marks quiz
I built a browser game for learning the Solent racing marks: a nautical chart, a highlighted buoy, and a multiple-choice question against the clock.
From workout planning to a Typst package
A small Typst package that turns a year and month into a grid you can write on. Built to stop hand-rolling monthly workout-planning sheets, now factored out and submitted to Typst Universe.
Wing foil sizing from first principles
A wing-foil gear calculator that shows its working. Three regimes (float, wing-in-air, foil-in-water) joined into one coherent physical model, with the equations exposed and arguable rather than hidden behind rules of thumb.

Understanding Ship Deceleration: Interactive Calculator and Mathematical Methods
How long does it take a ship to stop? I built an interactive calculator and worked through the hydrodynamics from first principles. Without friction brakes, we can see that hull form and propulsion type dominate stopping performance.
